My first attempt at bending the Casio SK-1. Most of the noises are pretty random, it' acts very much like an old school analog synth. The switches and knobs I added to this one are in 3 groups. An Image group, an axis group and a skew group along with pitch, poly and skew potentiometers. It also has a body contact that acts as a vibrato. Building this one was like doing heart surgery on a mouse...
